Abstract: A method for operating a diesel IC-engine being able to run in a conventional mode and in a partial Homogeneous Charge Compression Ignition (pHCCI) mode. The method comprises the features of switching the pHCCI mode from lean pHCCI to rich pHCCI as a response to a control signal indicating that the NOx-absorbent shall be regenerated.

Abstract: A system operates a hydraulic actuator, such as a cylinder, in one of several modes that include powered extension and retraction, self-powering regeneration modes in which fluid exhausting from one cylinder chamber is routed into the other cylinder chamber, and cross function regeneration modes wherein the fluid exhausted from one actuator is routed in the supply conduit to power a different actuator. A controller determines which modes are viable based on existing system conditions and selects from among the viable available modes. That determination is a function of the desired velocity for the actuator, the hydraulic load on the actuator, and pressures in the supply and return hydraulic conduits. The system also can recover potential or kinetic energy through pressure intensification which recovered energy can be used to power another simultaneously active hydraulic function or to drive the prime mover via an over-center variable pump/motor.

Abstract: A modification torque computing unit 83 computes a modification torque ?T and a torque converter speed ratio e is computed from input and output revolution speeds of a torque converter 31. A first determination coefficient ? corresponding to the speed ratio e, and a second determination coefficient ? corresponding to a pump pressure are computed. A selector 87 selects the smaller one of these coefficients as a determination coefficient ?, and the modification torque ?T is multiplied by ? to provide a modification torque ?TA. An adder 89 adds the modification torque ?TA (negative value) to a pump base torque TR to provide a modified pump base torque TRA, whereby a maximum pump absorption torque TRA is controlled so as to become TRA. The maximum pump torque reducing control can then be performed while accurately confirming a work situation during the combined operation of travel and a working actuator.

Abstract: A back surface of an outer case is formed by mutually overlapping left and right back panels. The overlapping edges on the front side and backside of the panels may be bent toward the opposite side at a blunt angle. A joint between the back panels is established in which the overlapping edge of one back panel is pressed against the overlapping edge of the other back panel. Spacers are mounted between the outer and inner case such that the overlapping edges are put in close contact with each other. The bends are deformed in order to prevent leakage from the joint after the injection of foam liquid. Due to the pressure of the foam, both of the overlapping edges are placed in closer contact while deforming the bends to be substantially flat. Consequently, the sealing properties of the joint after the completion of the thermally insulated housing are secured.
